In optics, an aperture is a hole or an opening through which light travels. More specifically, the aperture and focal length of an optical system determine the cone angle of a bundle of rays that come to a focus in the image plane. The aperture determines how collimated the admitted rays are, which is of great importance for the appearance at the image plane. If an aperture is narrow, then highly collimated rays are admitted, resulting in a sharp focus at the image plane. A wide aperture admits uncollimated rays, resulting in a sharp focus only for rays coming from a certain distance. This means that a wide aperture results in an image that is sharp for things at the correct distance. The aperture also determines how many of the incoming rays are admitted and thus how much light reaches the image plane (the narrower the aperture, the darker the image for a given exposure time). Like in the eye, the pupil is the aperture
Aperture controls so many variables in your images from
exposure to depth of field which can make it quite difficult
to gasp initially
A small aperture is a large f-number and a large aperture is a

This is my best picture as the image subject fills the screen so you focus on it straight away and i have changed the aperture so it snot to bright or dark and used a shallow depth of field to focus on the plant and blur out the background I also chose a darker plant that stands out against the green background which helps the image become very crisp and clear.
This is my worst picture as the focus on the leaves inst that good and most of the picture is very blurry due to a wrong aperture setting and it has effected the clearness of the picture.
